Futaba 3PM & Analog Servo Question

Hey guys, I hope you can help me with this.

I have a 3PM with analog servos in PPM mode. When the servos are idle, they don't make any sound, but when I blip the throttle or turn a wheel, I get a constant buzzing sound from the servos. When the servos return to idle, they will buzz for a few seconds and then stop.

Is this normal?
